Improvement in cider-mills



UNITED4 STATES PATENT OFFICE.

DANIEL SGULLY, OF BALTIMORE, MARYLAND.

IMPROVEMENT IN ,ClDER-MILLS.

Specification forming part of Letters Patent No. 43,434, ated .luly 5, 1864.

To all whom t may concern:

Be it known that I, DANIEL ScULLY, of the city and county of Baltimore, in the State of Maryland, have invented a new and useful t Improvement in Cider-Mills; and Ido hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making apart of this specification, and in which- Figure 1 is an isometrieal perspective view of my mill and press with the hopper in place. Fig. 2 is a transverse section through the cut ting and grinding cylinders, and Fig. 3 is a. planl view ofthe grinding-cy linders and their dri ving-gear.

It is the object of my invention to enable the cider-mill to do a 4larger amount otl work in a given time than any now in use Without requiring greater' power than these less effective ones require; and myinventicn consists in the employment in the cider mill of rotary and stationary cutters to divide the fruit by sharp cutting edges before it passes to the Crushing or grinding cylinders.

Upon a snit :ble flame, A, I mount a pair of grinding-rollers, a and a', over a receiving trough, B. 'Ihe grinding-rollers have angular or rounded teeth working into each other, and must be adjustable to vary their distance apart. -To render this adjustmentaceurate and simple I place thejournals of the roller a in stationary boxes, while the boxes that support the journals of roller a are permitted to move in slotted bearings, one of which is shown at b in Fig. I, and the position of these bearings is controlled at pleasure by the set-screws c and c', so that at any moment the pomace can be ground tine or coarse, as desired, or as the condition ofthe fi uit may require. A pinion, d, on the outer end ofthe shaft of roller a imparts motion to it, while the inner end thereof carries a cog-wheel, e, gearing with a-cog wheel, e', on the inner end ofthe shaft of roller a, and the motion of both rollers is equalized by a balance-wheel, f, on the inner end of the shaft of roller a', which balance-Wheel may also serve as adriving-pulley where power is used.

a box, g, to retain the fruit upon the rollers,

`surmounted by a hopper, h, having an adjustable slide gate, i, to regulate the feed. Within this box and over the grinding-rollers I place a rotating knifeleylinder, O, armed with two or more longitudinal parallel rows of knives, lc', placing the knives at such a distance apart in the rows as to pass freely between a stationary row of knives, kf, secured to the inside of the box g, and projecting toward and near] y to the rotating knife-cylinder. 'Ihe imite-cylinder O is supported on a shaft having its bearings in the box g, and the outer end of the shaft carries a cogvgear, I, that couples with and gives motion to the pinion d, tha-t rotales the grinding-rollers,while the gear l receives motion from the eranklarm m on the end of the shaft. y

AS the fruit is fed from the hopper, it is cnt between the. rotary and stationary cutters, and passes in slices from between them to the crushingrollers, where its reduction to any degree of iineness is easily effected and at the expenditure of the minimum power lrequired.

It is obvious that the speed of the lznit'e eutting-cylinder can be augmented at pleasure, and thus largely augment the effective capabilities ofthe mill without requiring as much power as is required to crush the whole fruit in the ordinary cider-mill, even' when doing aV less quantity of grinding. y

It is obvious that other fruits than apples, such as grapes and pears, can be reduced for the press in my mill.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of a rotating cutting-cylinder, the stationary knives, and the crushingrollers, arranged and operating substantially in the manner set forth.

In testimony whereof I have hereunto sul;- scribed my name.

DANL. SCULLY.
